Why does my iPhone Internet only work when u have a wifi connection?

[Mike Mustacchio]

My phone Internet only works when I'm at my house connecting through my own wifi.... Once I leave nothing that requires Internet such as my Facebook and twitter apps do not work... Why?

I have the iPhone 4s

What service provider do you have?

Perhaps you just disabled your mobile data

Have your provider hook you up with a direct link to the net.

Warning: it is gonna cost big time.

Depends on if you have Data or not. If you dont have data you cant access the internet without wifi. However, if you do have data you can access the internet whenever. Get a data plan, preferably unlimited because it costs alot to track your data and if you go over then it costs to much.
